GB 15579.1—2004/IEC 60974-1:2000 Except for Chapter 3 "Definition", which is a non-mandatory provision, the remaining provisions are mandatory. This part is equivalent to TFC60974-1:2000 Arc welding equipment Part 1: Welding power source. This part is consistent with GB15579—1995 Safety requirements for arc welding equipment Part 1: Welding power source"For DC systems, the maximum voltage shall not exceed 140V. For 60V (ripple-free) self-flowing systems, it shall not exceed 70V. 11FC:61558-1.3.7.1613.59
Plasma nozzle plasmatip
The component that provides the compression hole through which the plasma arc passes. 4 Environmental conditions
The welding source shall be able to operate normally under the following environmental conditions. a) Ambient air temperature range
During welding: -10℃·40℃;
During transportation and storage: 25℃-~-55℃. ) Relative humidity
At 40℃, it shall not exceed 50%
At 20℃, it shall not exceed 90%
c) Dust, acid, corrosive gas or substance in the ambient air shall not exceed the normal content, except for these substances generated by the welding process.
The altitude should not exceed 1000m,
c) The inclination of the welding power source should not exceed 15 Note: The manufacturer and the user can agree on the environmental conditions that are not connected to the grid.
